PAPER-TRANSMITTING MECHANISM.

Application filed January 14, 1904, Serial No. 188,942. Renewed May 4,1905.

T 0 all whom it may concern:

Be it known that I, WILLIAM T. BAILEY, residing at Elmira, in the countyof Chemung and State of New York, have invented certain new and usefulImprovements in Paper-Transmitting Mechanism, of which the following isa full, clear, and exact description, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to web-handling machinery and, more particularly,to means for cutting and creasing a web of paper.

One of the objects thereof is to provide simple and efficient means foraccurately creasing a web along a predetermined line without bringing anundue stress thereon and evenly folding portions of the same into thedesired form.

Another object is to provide practical and compact means for cutting aweb into portions of uniform length.

Another object is to provide means adapted efliciently to remove a webafter being acted upon by one or both of the above means.

Other objects will be in part obvious and in part pointed outhereinafter.

The invention accordingly consists in the features of construction,combinations of elements and arrangement of parts which will beexemplified in the mechanism hereinafter described and the scope of theapplication of which will be indicated in the following claims.

In the accompanying drawings. wherein is shown one of various possibleembodiments of several features of my invention, Figure 1 is a sideelevation of the same; Fig. 2 is a similar view of parts shown in Fig. 1upon a larger scale.

Similar reference characters refer to similar parts throughout bothviews.

As tending to render clearer certain features of my invention, it mayhere be noted that if it be attempted to crease a web which is being fedunder tension, there is a considerable stress brought to bear upon thesame during the creasing operation and unless this stress is relieved orprovided for there is a possibility of injury to the web. It may alsohere be noted that if ample slack be provided for the action of thecreasing mechanism, there is a marked likelihood of Specification ofLetters Patent.

the web being excessively loose with a consequent absence of uniformityin the folded sheet. The above and other defects are remedied inconstructions of the nature of that hereinafter described.

Referring now to Figure 1 of the accompanying drawing, there are shown apair of cylinders 1 and 2, which may be provided with perforatingmechanism 3, if desired. Between these cylinders is led a web, as from amill roll 38, which passes into a sheet path 12 leading to a second pairof cylinders 5 and 6. Cylinder 5 is provided with creasing blades 7adapted to coact with gripping mechanism 8 upon the cylinder 6, andthere are also mounted upon cylinder 5 a pair of cutter blades 10operatively related to coacting parts 11 upon the lower cylinder 6. Thiscreasing and cutting mechanism, which is neither shown nor described indetail as its specific form is not involved herein, is intended to actupon the web fed from the sheet path 12, severing the same into sheetsand folding each sheet at the center. Stripping mechanism 14: leads thefolded sheets by tapes 15 into a sheet path 16 from which any desireddisposition may be made of the same.

Mounted adjacent the web at a point before the same enters cylinders 5and 6 is a bar 13 revoluble about an eccentric axis and so driven as tostrike the web and deflect it from a straight path between the tapes 12and the cylinders, thus retracting a portion of the web. This action isperhaps best shown in Fig. 2 of the drawings, the deflected condition ofthe web being indicated by dotted lines.

It may here be noted that the term retract is used throughout in a broadsense as denoting any action by virtue of which a member is either drawnback relative to stationary parts, or the rate of its travel diminished,and the same thus drawn back relative to the parts fed at the normalrate of travel.

The operation of the above described embodiment of this invention is asfollows: The parts are all mounted in suitable sup porting frame workand so geared together by any approved mechanical connections as to bedriven 'at the proper rate of speed to accomplish their functions. Theweb is fed to the cylinders 5 and 6, and assuming that one of the cutterblades 10 has severed a sheet and permitted the same to pass within thetapes 15, the free severed edge of the web is carried forward, thusbringing the following creasing blade 7 toward its operative position,as best indicated in Fig. 2 of the drawings. As shown in the method ofdrive indicated in this figure, the bar 13 strikes the web ust prior tothe action of the creasing blade 7, and starts to deflect the same orgather slack at this point, retracting portions of the web. The actionof he creasing blade which takes place sub stantially at this time is toforce the web within the gripper, or its equivalent, upon the cylinders6, the bar 13 being so disposed and driven as to permit this action andyet maintain the web stretched evenly and tautly in such manner as toprevent lack of uniformity in the point of folding the severed sheets.That is, the bar 13 is so timed and driven with relation to theremaining parts that the creasing blade shall always actat exactly thesame distance from the free severed ed e of the web, any slackness orunevenness being obviated by the intermittent tautening action of thispart. Subsequent to the creasing action, the fold is carried forward andstripped from the cylinders by the part 14: from which it passes to thetapes 15, as above described, the web being severed by the followingblade 10. It is to be understood that the web is fed by the tapes 12 tothe cylinders at such rate as to provide suiiicient slack for theefficient action of the creasing means, as above set forth.

It will thus be seen that I have provided means for accomplishing theobjects of my invention which are of simple and inexpensiveconstruction, and, owing to the lack of complicated mechanism, are notlikely to become deranged during use. Injury to the web is positivelyprevented by reason of the slack given th creasing means, which is soarranged as to permit free action thereof and yet obviate any lack ofuniformity or certainty in the operation of the machine. By the use ofthe intermittently active bar in conjunction with the necessarilyintermittently acting creasing blades, there is provided a pair ofnicely coacting elements, the former of which so manipulates the sheetas to render it in precisely the proper condition through each point ofoperation of the creasing mechanism. Moreover, as the several parts areentirely automatic in action and excessive tension upon the web isavoided, the degree of supervision is reduced to a minimum and breakingor tearing of the web with a consequent loss of time and material is ofrare occurrence.

It may here be noted that the expression substantially simultaneously isused throughout the following claims as descriptive of the relativetimes of action of the creasing means and the mounted bar 13 in a broadsense denoting that these mechanisms are oper tive at the same time,although in the preferred action of the above described machine the bar13 first strikes and tautens the web and then gradually releases thesame so as to hold the web smoothly over the creasing blade, and yetgive up sufficient slack to insure of free action of the latter member.

As many changes could be made in the above construction and manyapparently widely different embodiments of this invention could be madewithout departing from the scope thereof, it is intended that all mattercontained in the above description or shown in the accompanying drawingsshall be intepreted as illustrative and not in a limiting sense.
